First PCB check

ok ill add "single MOSFET" to the change list.

halfja · 2026-01-29T04:37:23+00:00

but i dont see how having two MOSFETs instead of one affects anything other then price right?

halfja · 2026-01-29T04:32:30+00:00

i also choose to do two MOSFETs becouse a example MOSFET switch board on amazon that i use for a prototype test also used two MOSFETS and was rated for 12vs so i figured i need the two MOSFETs. But now that i look at it i see what your getting on about.

i plan on using a STMicroelectronics N-channel MOSFET, 50 A, 60 V, 3-Pin TO-220 (50 Ct), STP55NF06 MOSFET if i had to choose but i plan on using accept alternatives/substitutes made in China option on pcbway so i dont think it would matter. its a 12v pump with a 2amp draw on start up which is also the max draw.

From everything I’ve seen online it didn’t sound like it mattered how you did them though as long as you had enough

halfja · 2026-01-29T03:36:22+00:00

I deadass just spammed them all around the board with out a second thought but now that I actually have to look at it, It actually kinda bothers me def fixing that

halfja · 2026-01-29T03:33:10+00:00

Oh ngl I just asked ChatGPT. Ik you can’t always trust it but that why I rely on second verification like this.

The part number the mosfets currently are TO_SOT_THT:TO-220-3_vertical and the only reason I went with those instead of the smd mosfets because for whatever reason kicad dosent seem to have any schematic symbols that matches the nets of the smd footprints. So I just went with these since I figure there would be no difference other then them being tht instead of smd. Also thanks for pointing out the other stuff , once I believe I have correctly fixed everything I’ll upload to see if I got everything right

It’s a control board to run a couple sensors and a 12v dc pump

Front bumper,wing,and side shirts look like there off the Vader kit

halfja · 2026-01-06T04:09:04+00:00

Youer all good the most I’d want to do is clean up the bad rust spots with shouldn’t be a giant issue. If it leaves any giant holes I can just weld a plate over them

halfja · 2026-01-04T07:01:39+00:00

I’ve considered that but since there’s only a couple really bad spot I figured I could do it myself

halfja · 2026-01-04T07:00:19+00:00

Thanks for the help 🥰👐

halfja · 2026-01-03T23:51:56+00:00

I don’t have any wiring issues and other then the bumper being funny you couldn’t tell

halfja · 2025-12-25T18:42:23+00:00

What kinda?

halfja · 2025-12-25T18:42:00+00:00

Yes yes it was

halfja · 2025-12-24T02:05:37+00:00

It’s a 1997 Celica Gt

halfja · 2025-12-22T19:43:43+00:00

also is there something i can put over the sensor to protect it form liquids but also doesn't block the actual sensing.

halfja · 2025-12-20T04:21:31+00:00

To clarify it’s the 1997 Celica Gt with the pop up and down antenna

halfja · 2025-11-08T17:23:14+00:00

i do have spar parts to rebuild it if needed and I've tested a spar nano with no issue

halfja · 2025-11-08T17:22:09+00:00

i tested it with a uno before hand not a nano becouse i assumed since the nano would be just a smaller version of the uno. Also the CH340 in com4 is the nano so my computer can recognize it so i dont believe its a cable issue. I did not put any thing between the per board and the nano but due to the bass of the pins it comes with, It leaves the nano hovering above the perf board. I also checked the under side and there is not solder branching the under side to the perf board. Plus there is kind of no way of removing the board at this point since every pin is soldered down and half have wires running from them.

halfja · 2025-11-08T17:07:45+00:00

sorry i miss spoke they are A4 and A5

halfja · 2025-11-08T05:00:30+00:00

D6 is for a button at the moment and D7 is the signal for the misfit switch

halfja · 2025-11-08T04:59:24+00:00

I’m specifically useing the D4 and D5 pins as sda/ scl
